Abstract

An electric rocker switch has a thermally responsive moveable contact element (16) that is mechanically closed against the fixed contact (14), but moves by bimetallic thermal action to open when an overcurrent condition exists. A trip flag (30) also moves between the open contacts (14,18) whenever the switch rocker is moved to OFF, and will remain in this position even if the rocker is held ON, if the bimetallic element (16) has caused the flag (30) to move between the contacts (14,18). Trip-free operation is thereby achieved. A spring (32) acts on the trip flag (30) to provide a positive snap action as the flag (30) moves between the contacts. The same spring (32) holds the rocker ON, and serves to hold the flag (30) lightly against the movable contact (18) in the switch ON condition. <IMAGE>
